Does anyone know if applications are screened based on your adress on your CV?
For example if you are up north and applying to jobs in london will they ignore CV?
Depends, if it was a training contract in a law firm they would like to see some local connection so that they can have some comfort that you won't leave the second you qualify to return from whence you came. I couldn't speak for any other sector though, although it seems this is likely a concern in most similar roles.
